Steven Cohen's ex-wife has hired the same lawyer as the Boston Marathon bombing suspect's widow.

Joshua Dratel is set to become Patricia Cohen's fourth lawyer in her racketeering lawsuit against the SAC Capital Advisors founder as soon as today. The hire comes just days after Cohen's last lawyer, Howard Foster, sought permission to withdraw from the case.

Dratel, a Harvard Law School graduate, is a New York trial lawyer with racketeering experience. But he's best-known for his representation of terrorism suspects. Earlier this month, he was hired by Katherine Russell, the widow of Tamerlan Tsarnaev, the Boston suspect killed in a shoot-out with police last month. Russell has not been accused of any wrongdoing.

Patricia Cohen's explosive lawsuit against her ex-husband was reinstated last month. In the racketeering suit, she alleges that Steven Cohen hid $5.5 million from a real-estate settlement during their 1991 divorce, and is seeking $8.5 million in damages. The suit, in which Patricia originally sought a controlling stake in SAC, was dismissed in 2011, but was revived by a federal appeals court in April.

SAC has called the lawsuit little more than an extortion attempt, and Steven Cohen's lawyers are expected to seek its dismissal again.

Patricia Cohen announced plans to hire a new lawyer after the U.S. Second Circuit Court of Appeals restored her case. At the time, Foster was said to have been given the option to remain on the case; he said in Monday's filing that the split was "a mutual decision."
